Well I get them sorta often, it usually depends how turned on I am.
Other then that I hardly ever get them, like if I'm going to have a wank then I wont get a nosebleed because I'm thinking about sex/whatever.
But if I'm in a place that might not be suitable for anything sexual, say school lol or something like that and I'm thinking about sex because I'm bored, I'll get a nosebleed. Thats only sometimes tho, its almost like they only happen in ironic places like at school around my friends.
They only last a few seconds and they are really only just a single line of blood that runs down my nose. It clots soon after. I asked my doctor a long time ago and she said its perfectly normal for a person my age.
